XR refers to all real-and-virtual environments generated by computer graphics, which includes augmented reality (AR), mixed reality (MR), and virtual reality (VR), as in Fig. REF .
Deploying XR over wireless communication networks is an essential step for realising XR applications [1]}.
Due to the seamless and immersible requirements, it is important to introduce wireless communication technologies to meet the stringent quality of service requirements, such as high data rate and ultra low latency.
For XR allocation over wireless communications, the location and orientation information needs to be sent to the BSs and the BSs construct the 360 degrees images for users based on the received information
